ADOOM on A600 running 22-35 FPS

The problem with pc-task is that the timing is all sorts of wrong.
Even on my amithlon box (which reports to be running 68040@4800 mips (seems pretty close to actual speed)) the timing goes crazy, even when assigning 256Meg to the translation cache/buffer.
It's nice and fast, but it's inconsistent. Two seconds at about 100 fps for ms-dos quake, then 1 second at about 3 fps. Probably hasn't been noticed by many people as there's very few machines running 68k code as fast as my amithlon box (c2d@4.05ghz).

Win9x does work, but you're limited to vesa.
All in all it's probably the best possible option for 68k systems when it comes to pc emulation, but don't expect it to be a great option, regardless of speed for some tasks.
Considerably faster than Dosbox, but not as consistant, nor does it emulate particular hardware as Dosbox does (gfx is a simple vesa frame buffer in pc-task). Neither is ideal, but between the two you can get a pretty good experience if you have enough grunt.

As for ADoom on the a600, that's not too bad at all. Roughly half of what I used to get on my 1st Pentium system, which isn't bad for an a600.

How long is a piece of string?
Seriously, that's so vague as to be unanswerable. Im not sure you even truly understand what youre asking, or else you'd have asked a question that can be answered in a way other than "how long is a piece of string"  :-)

Maths units? Interger or floating point? Also, just adding extras doesn't automatically make it faster.

Again, simply saying "maths unit" is vague to a point of it not really meaning much.
I assume it's meant to be floating point units, but that's not what has been said.

Also, *any* gpu will help a 68k cpu. Voodoo3, radeon 9200, heck even s3 virge.
There's little point in adding anything better than whats available anyway. GPU's need cpu grunt to get the most from them. Adding support for anything faster will add pretty much nothing.
It's amazing how many people are under the impression that a gpu is enough. It's not. It needs cpu grunt to get the most from a gpu.
For example, running a 5ghz i7 + radeon hd 5850 is often faster (especially for minimum framerate) than a 3.4ghz i7 + crossfire 7970's.
